Berman's book actually consists of additional chapters of arithmetic and can serve to increase arithmetic culture for a wide range of readers. Along with the rules for multiplying fractions, it outlines rules for calculating roots and approximate multiplication, which may be interesting for a qualified reader. In the third edition of the book, edited by A. L. Harmful, small clarifications were made. The most important of them are as follows: The old name "Fast counting techniques" is replaced by the name "Counting techniques," since the book has nothing to do with computational foci and pop computing techniques. In the section on the written solution of interest problems, instead of three arithmetic rules, one algebraic is given, which is remembered mnemonically. Slightly changed and expanded section on square roots.
